Cage-Free Pullets Minimally Affected by Stocking Density Stressors [PDF]

Animals
Management choices during the pullet phase can affect behavior, welfare, and health later in life, but few studies have evaluated the pullet phase, particularly in extensive housing systems.

Animal welfare indicators and stress response of broiler chickens raised at low and high stocking density [PDF]

Journal of Animal Science and Technology
Stocking density is a crucial parameter that impacts animal welfare, performance, and economic returns for producers. In our current investigation, we explored the influence of stocking density on the growth performance, litter quality, footpad ...

Effect of classical music on growth performance, stress level, antioxidant index, immune function and meat quality in broilers at different stocking densities [PDF]

Frontiers in Veterinary Science, 2023
High-stocking density is one of the factors that can easily cause oxidative stress and inflammatory reaction of broilers. Currently, music therapy has been proposed to help animals relieve stress to some extent.

Fecal microbiome analysis uncovers hidden stress effects of low stocking density on rainbow trout [PDF]

Animal Microbiome
Background Recirculating aquaculture systems can cause chronic stress in fish when stocking density is too high. However, this study tested whether low stocking density can cause fish stress.

Effect of stocking density and age on physiological performance and dynamic gut bacterial and fungal communities in Langya hens [PDF]

Microbial Cell Factories, 2021
Background The characterization of colonization and dynamic changes related to gut microorganisms might be vital, as it presents an opportunity to quantify the co-variation between stocking densities and gut microbiome of dynamic distribution.

Effect of Stocking Density on Behavioural and Physiological Traits of Laying Hens [PDF]

Animals
This study analysed stocking density as a major stress factor for laying hens and assessed its impact on selected behavioural and physiological traits of the birds. The study population included 142 birds of the Green-legged Partridge breed (12 males and

Effect of Stocking Density during CO₂ Stunning of Pigs on Induction Time and Activity Level Measured Using AI [PDF]

Animals
During the CO2 stunning of pigs, a variation in their reaction to the gas and the duration of the induction period is observed. The stunning process can be affected by several conditions, such as stressful events and previous experiences, but the ...

Stocking density-induced changes in growth performance, blood parameters, meat quality traits, and welfare of broiler chickens reared under semi-arid subtropical conditions.

PLoS ONE, 2022
Broiler production in semi-arid tropics must contend with high levels of heat stress, which have implications on stocking density, bird welfare, and profitability.
